my lo is currently 3 mths plus old..these 2 days he seems to fuss a bit when I bf him..is it a sign that he wants to wean off? What should I do? I don't Wan to stop bf so soon...

I don think is a sign of weaning off but at 3 mths stage, he might be having a growth spurt. During this phase, all the feeding and sleeping pattern might change. It will be a trial and error period for parents to see what the baby wants and accommodate accordingly.
